An experiment is a question which science poses to Nature and a measurement is the recording of Nature’s answer. - Max Planck 1858 to 1947 Theoretical Physicist
With monads and diads and pentads and triads My brain has been addled completely; And what’s really meant by ‘something-valent ’ Is a question I give up discretely. ~ John Cargill Brough - 1834 to 1872

Chemistry is necessarily an experimental science: its conclusions are drawn from data and its principles supported by evidence from facts. ~ Michael Faraday - 1791 to 1867
What is possible in the Cavendish Laboratory may not be too difficult in the sun. - Sir Arthur Eddington 1882 to 1944 Astronomer Physicist Mathematician
I see some parallels between the shifts of fashion in mathematics and in music. In music the popular new styles of jazz and rock became fashionable a little earlier than the new mathematical styles of chaos and complexity theory. Jazz and rock were long despised by classical musicians but have emerged as art-forms more accessible than classical music to a wide section of the public. Jazz and rock are no longer to be despised as passing fads. Neither are chaos and complexity theory. But still classical music and classical mathematics are not dead. Mozart lives and so does Euler. When the wheel of fashion turns once more quantum mechanics and hard analysis will once again be in style. ~ Freeman Dyson b. 1923 - Mathematician and Physicist

I am not insensible of the advantage which accrues to Applied Mathematics from the co-operation of the Pure Mathematician and this co-operation is not infrequently called forth by the very imperfections of writers on Applied Mathematics. ~ Ronald Fisher 1890 – 1962 - Mathematician Statistician Evolutionary Biologist
All increasing or dominant species (and it is from these that new species arise) vary considerably in all their parts organs and faculties in every generation. ~ Alfred Russel Wallace 1823 to 1913 - Zoologist Evolutionary Biologist
